INK-FOUNTAIN FOR PRINTING-PRESSES.

Specification of Letters Patent.

Application filed July 22, 1912.

ments in a printing press ink fountain of the class that has a fountain back, a fountain frame, a fountain blade and a fountain roller.

It comprises improved means for adj usting the fountain blade as a whole relatively to the fountain roller in a direction parallel or approximately so with the plane of the said blade and for taking up wear in the latter.

It comprises also improved means for allowing the entire fountain blade and entire fountain back to be taken, as a whole, a 'ay from the fountain frame.

It comprises also improved means by which the fountain blade and fountain back can be taken, as a whole, away from the fountain frame without disturbing the serpentine adjustment of the edge of the said blade, and can be put back again without damaging the said edge.

A preferred form of the several means above enumerated, is illustrated in the accompanying drawings in which- Figure 1 is a side elevation from the feeder side of the press; and F 2, an elevalion from the front end of the press, of the right hand half of the said form. The left hand half is a replica of this right hand half.

leferring thereto, the fountain back 1 is aifljnstable upon the fountain frame 2 with reference to the fountain roller 3, by an ad justing device at each end of it, the two devices being independent of each other. Each of these two devices consists, preferably, of a milled head screw t engaging in a front to rear direction, in. the fountain back 1. and having a pair of collars 5, 6, fast on it, and a slotted bracket or abutment 7 adapted to engage between the said collars and to be disengaged therefrom by being pivoted on a pivot 8 projecting to the front and outside the respective screw 4, from the respective end. of the fountain frame 2. Consequently, the farther these screws 4 are screwed into the fountain back 1 when the brackets 7 are engaged with them, the farther will the edge of the fountain blade 9 stand from the fountaln roller 3. The pivots 8 may be replaced by set screws or their equivalent, engaging in the fountain frame 2 in such a way as to lock the brackets 7 when the latter are engaged with their screws f, to prevent anv liability on the part of the said brackets to be disengaged from their screws when the latter are beingturned. Thus referring to Fig. 2, 8 is to be taken as the head of a set screw, the shank of which passes through the respective bracket 7 and engages in the fountain frame 2, thereby serving as the pivot of the said bracket, the head of the set screw serving to lock that bracket by being turned into the said frame till it pinches the bracket between itself and the frame.

There are two suitable grips f) symn'ietrically arranged on the fountain back 1 by which the attendant can easily move it and the blade 9 from the fountain frame 2, after he has disengaged both the brackets 7 from the respective screws 4.. a Thus adjusting energy is applied to the blade at both ends of it and only to the ends of it, and to the whole of it at once.

The fountain back 1 is locked to the frame 2 in its adjusted position on the latfor, by a row of T headed screws 10 passed a up through front-to-rear slots 11 in the said frame end screwed into the fountain back 1.. Thus, the entire fountain blade and entire fountain back can be taken, as a whole, awav from the fountain frame. I

The edge of the fountain blade 9 has always been a spring one and the fountain frame 2 has had a row of set screws vertt cally adjustable in it for setting the respective portions of its edge up toward the roller 3 in a line other than parallel with the surface of the said roller, and one which may be either at an angle with or serpentine with reference to it. If the back ,1 and blade 3 were then moved away from the said roller, the edge of the blade would be moved off the said set screws and would spring back to its normal line. Subsequent attempts to return the back and blade to their original positions would damage the blade edge against the set screws. According to the present invention, the said row of set screws 12 work, not in the fountain frame 2, but in the fountain back 1 and as the blade 9 is fast to the latter, no movement of the said blade from the roller 3 can move it off the I screws 12, nor movement of it toward the said roller, damage its edge against them.

The fountain as a whole is adjustable upon the main frame 13 of the press, to and from the ink ductor roller 14 by an adjusting device at each side of the front end of the fountain frame 2, the'two adjusting devices being independent of each other. This position of the two adjusting devices and their independence of each other, is important, because it provides for the adjusting motion of the fountain being always parallel with the ductor roller. Each adjusting device consists, preferably, of a milled head screw 15 engaging in the fountain frame 2', lengthwise of the press, and having two collars 16, 17, fast on its shank, and a slotted bracket orabutment 18 fast to and projecting to the front from the respective side frame 13 of the'press; the said screw 15,

collars 16, 17, and bracket 18 being so positioned relatively to each other, that the shank of a screw 15 turns 1n the slot in the bracket 18 and the two collars 16, 17, respec tively bear against the front and rear faces of the said bracket. 1 Having described our invention, we declare that what we claim and desire to secure by Letters Patent is 1. The combination in an ink fountain having a fountain frame, a fountain blade,

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of and a fountain roller, of a fountain back adjustable upon the fountain frame relatively to the fountain roller; anadjusting screw at each side of the fountain back and work ing in it along a line parallel with the adjusting motion of the said back upon the fountain frame; a pair of collars fast upon each of the said screws; and an abutment carried by each side ofthe fountain frame, capable by being pivoted on the latter, of

being engaged with the respective screw be-.

tween its collars and of beingdisengaged therefrom. I

2. The combination in an ink fountain having a fountain frame, a fountain blade, and a fountain roller, of a fountain back adjustable upon the fountain frame relatively to the fountain roller; an adjusting screw at each side of the fountain back and working in it along a line parallel with the adjusting motion of the said back upon the fountain frame; a pair of collars fast upon each of the said screws; an abutment carried by each side of the fountain frame, capable by being pivoted on the latter, of being engaged with the respective screw between its collars and of being disengaged therefrom; and means for locking each abut-- ment in either of its twopositions.

In witness whereof. we have hereunto set our handsin the presence of two witnesses.
